To determine the decimal that represents the portion of the model that is shaded, you would typically compare the shaded area to the total area of the model.
Since I can't see the image you referenced, I'll guide you based on common fractions. Typically, if a model is divided into a certain number of equal parts, the fraction of those parts that are shaded can be converted to a decimal.
- If 3 out of 10 parts are shaded, that's 0.3.
- If 33 out of 100 parts are shaded, that's 0.33.
- If 67 out of 100 parts are shaded, that's 0.67.
- If 7 out of 10 parts are shaded, that's 0.7.
If you can provide details about how many parts are shaded or a description of the model, I can help you further narrow down the correct decimal representation.
